In this webinar, we will examine how immune recognition after allogeneic HCT can influence leukemia relapse and disease progression. The session will highlight the clinical relevance of HLA loss of heterozygosity (LOH), approaches used for its detection, and how LOH findings may support transplant strategies, including considerations for donor selection in subsequent transplantation.

Webinar presenter Alberto Cardoso Martins Lima, PhD, Clinical consulting scientist in histocompatibility,
specializing in allogeneic hematopoietic cell transplantation (HCT) at IGEN/AFIP São Paulo and CHC/UFPR in Curitiba, Brazil

Moderated by: Bob McGonnagle, Publisher, CAP TODAY

Wednesday, June 24, 2026, 12:00–1:00 PM ET
Hear an expert discuss the expanded clinical utility of HER2 IHC scoring in metastatic breast cancer and its impact on your practice

Webinar presenter Michelle Shiller, DO, AP, CP, MGP, FACP, Baylor University Medical Center.

Wednesday, July 15, 2026, 1:00-2:00 PM ET
Hear an expert discuss how to integrate Kappa and Lambda in situ hybridization testing into your standard hematopathology workflow to accurately assess B-cell and plasma cell clonality. You will also gain the skills to recognize testing pitfalls in challenging reactive versus neoplastic proliferations and apply ancillary tools to resolve complex cases.

2023 Issues

From the President’s Desk

June 2023—I embarked this year on my first international travel as president of the CAP. Due to limitations from the pandemic, I haven’t been able to do as much of this as some of my predecessors, but happily this year we seem to be finally coming out of the worst of it.

 

Clinical pathology selected abstracts

June 2023—Studies that address whether the incidence of dementia in the U.S. population is declining are inconsistent. They cannot establish conclusive trends in disease rates. Most studies are hard to interpret due to small sample sizes or use of hospital-based autopsies. Understanding trends in dementia is necessary from a public health perspective and for planning interventions. Therefore, the authors conducted a study to characterize trends in pathways underlying dementia using two U.S. cohorts focused on aging and dementia.

 

Anatomic pathology selected abstracts

June 2023—The authors conducted a study to examine whether quantitative digital pathology can derive valuable information from readily available and inexpensive H&E slides and thereby augment routine pathologic reporting of colorectal carcinoma. They applied a quantitative segmentation algorithm (QuantCRC) to 6,468 digitized H&E slides of colorectal carcinoma (CRC). Fifteen parameters from each image were recorded and tested for associations with clinicopathologic features and molecular alterations. A prognostic model was developed to predict recurrence-free survival using data from the internal cohort (n=1,928) and validated on an internal test (n=483) and external cohort (n=938). There were significant differences in QuantCRC according to stage, histologic subtype, grade, venous/lymphatic/perineural invasion, tumor budding, CD8 IHC, mismatch repair status, KRAS mutation, BRAF mutation, and CpG methylation.

 

 

Molecular pathology selected abstracts

June 2023—Endometriosis is defined by the presence of endometrial-like tissue outside of the uterus and can cause debilitating pelvic pain and often infertility. It has also been associated with a range of reproductive, metabolic, inflammatory, and chronic pain conditions. While it is fairly common, affecting five to 10 percent of women of reproductive age, treatment options are limited, and the precise causes of endometriosis, as well as its relationship with other conditions that cause chronic pain, remain unclear. Studies estimate that endometriosis has a heritability of approximately 50 percent. Nine genomewide association studies (GWAS) of endometriosis involving women of European and East Asian ancestry were reported prior to this study.

 

Q&A column

June 2023
Q. California Senate Bill 864 requires that fentanyl screening be included in every drug screen performed in a general acute-care hospital laboratory. The problem is there are no FDA-approved platforms for rapid screening of fentanyl. I found several for forensic use only. The only reagents I found are third-party products to run on open channels on large chemistry analyzers. This is a huge amount of work and expense for a small laboratory. Is sensitivity the stumbling block for rapid testing? How useful is a urine screen if an overdose is an immediate effect and it takes hours for fentanyl to show up in urine and then another hour to run it on a chemistry analyzer? Read answer.
Q. How should a laboratory calculate analyzer throughput? Has a formula been published? Read answer.

June 2023—The time it takes to read through numerous pathology reports to find nuggets of critical information buried within narrative sections of text is tantamount to the time it takes for carbon atoms to turn into diamonds—or so it may seem to those tasked with digging for medical information.

 

Put It on the Board

June 2023—The Association for Molecular Pathology and the National Society of Genetic Counselors released in May a report containing eight recommendations for next-generation sequencing germline variant confirmation.

 

Colorectal cancer next on HER2 horizon

May 2023—Behold the common coin. Note its two sides, its easy flippability. Here is Joseph Pizzolato, MD, with the first coin toss. Given the expanded use of biomarkers with a variety of tumors, and constantly evolving assays, how hard is it for medical oncologists to navigate testing? “It’s not difficult at all now,” says a cheerful Dr. Pizzolato, medical director of the comprehensive therapeutic unit of Sylvester Comprehensive Cancer Center, University of Miami Health System, as well as medical director of the Aventura satellite at Sylvester. With third-party companies integrating test ordering directly into electronic medical records, he adds, “It’s getting even easier to order tests and see the results.” Agreed, says his colleague Rhonda Yantiss, MD, director of surgical pathology, Department of Pathology and Laboratory Medicine, University of Miami Miller School of Medicine. And therein lies the problem. “It’s kind of a mess,” she says. In practice, precision medicine is becoming both more and less precise.

‘Hundreds of variants’—Staying alert to HbA1c method interference

May 2023—Of the five methods used to measure HbA1c—immunoassay, boronate affinity, enzymatic, capillary electrophoresis, and ion-exchange HPLC—only the latter two can alert the laboratory and physician to the presence of a suspected hemoglobin variant. Even so, there are reasons to be cautious.
